cgen error: '__v_error' undeclared

[Coachonko]

Describe the bug

module main

import os
import io
import coachonko.luuid

fn prepare_response(s string) []u8 {
	return '${s}\n'.bytes()
}

// commands end with `\n`
fn main() {
	mut generator := luuid.new_generator()
	stdin := os.stdin()
	mut b_reader := io.new_buffered_reader(reader: stdin)
	mut stdout := os.stdout()
	// TODO this sort of loop kills the processor, another ipc technique must be utilized instead.
	for {
		line := b_reader.read_line() or {
			dump(error)
			break
		} // TODO exit loop when eof and pipe closed. should only be when pipe closed.
		println(line)
		if line == 'v1' {
			id := generator.v1() or { 'error' } // TODO handle error
			res := prepare_response(id)
			_ := stdout.write(res) or { 0 } // TODO when could it fail?
		}
	}
}

Reproduction Steps

Accidentally wrote dump(error) instead of dump(err) and got the cgen error when compiling the program.

Expected Behavior

Compiler should tell me error is undeclared instead of producing bad c code

Current Behavior

bad c code

Possible Solution

No response

Additional Information/Context
